B. L. ('BILL') BURTT (27 AUGUST 1913 TO 30 MAY 2008)

From: Quentin Cronk [quentin.cronk@ubc.ca]

Brian Laurence Burtt, always known as Bill to his friends and colleagues,
has died aged 94. He was one of the prodigious botanists of the 20th century
and along with Peter Davis, was in large part responsible for establishing
the Royal Botanic Garden Edinburgh (RBGE) as a renowned scientific research
centre.

BLB's great strength was as a critical observer, a skill that was finely
honed when he worked before the Second World War as assistant to the
Director, Sir Arthur Hill, at the Royal Botanic Gardens, Kew. Hill loved
oddities of plant structure (as exemplified by Hill's papers of germination
of seeds with stony endocarp and resupination in flowers). As Director of
Kew, Hill had limited time to seek out nature's curios in the Kew living
collections so he engaged BLB as his young assistant to do it for him. Hill
encouraged him to go around the living collections and "observe". This early
training was formative in developing BLB's taxonomic genius. He picked up
from Hill an interest in germination and thought it a pity that a major
botanical garden like RBGE, growing annually thousands of plants from seed,
did not keep systematic records of seedling morphology and mode of
germination.

BLB joined RBGE in 1951, where he developed important research programmes on
a variety of plant families but particularly Gesneriaceae ("gesners" - his
great love) and Zingiberaceae (in collaboration on Rosemary Smith). The bald
facts speak for themselves. He collected 19,102 herbarium specimens,
authored 382 papers and described 637 new species, mostly gesners, but also
in numerous other families, including Asteraceae, Zingiberaceae,
Umbelliferae and Scrophulariaceae (H.N. Noltie, pers. comm.). His essay on
the Compositae (Burtt, 1961a) is still a wonderful introduction to that
family. In 1964 he formed a professional and personal collaboration with
Professor Olive Hilliard of the University of Natal. This collaboration led
to large numbers of papers but also to three remarkable illustrated books
(Hilliard and Burtt 1971, 1987, 1991).

BLB saw deeper into the plant than most taxonomists and had the intellectual
ability to place what he saw in an intellectual framework that allowed the
information to be captured, rather than skated over as a puzzling oddity.
This is nowhere more evident than in his important observations, and
intellectual contributions, on anisocotyly and the unifoliate habit in
Streptocarpus (Jong and Burtt 1975). It also informed his taxonomy, making
him a big picture taxonomist, able to organize intellectually whole
families, not just the genus he was working on (Burtt, 1963, 1972, 1991;
Burtt and Smith 1972; Burtt and Wiehler 1995). His interest in plant
morphology as part of functional evolution led to a number of
thought-provoking contributions, some of which are listed in the references
here (Burtt 1961b, 1970, 1974, 1994).

In the Streptocarpus book (Hilliard and Burtt 1971) BLB talks of the
pleasures and necessity of dividing time between field, laboratory and
herbarium - a clear statement of the importance he placed on the study of
the living plant. One of my most abiding memories of BLB was being in the
field with him (at age 85) on a visit to Mt Kinabalu. BLB had described the
gesners of the 1961 and 1964 Royal Society expeditions to Kinabalu, but had
never been there. So he was seeing plants he had described many years ago as
new to science, but he was seeing them in the live state for the first time.
He greeted them all as old friends and was interested to see what they
"really" looked like!

BOTANY BC 2008

From: Chris Pielou, Sharon Niscak and Helen Robinson

This years Botany BC was held May 15  17, 2008 at Powell River, with trips
to Texada Island and additional informal trips to Savary Island on Sunday.
Nick Page and Elizabeth Easton skillfully arranged all the details with the guidance of
local naturalists, Terry Ludwar and John Dove, and the blessing of perfect
weather.

On Thursday evening we gathered at the Italian Cultural Centre for delicious
appetizers while renewing acquaintances and meeting new botanists. Elsie
Paul welcomed Botany BC participants to the Sliammon territory in the spirit
of her traditional name, Qaxustala, meaning a welcoming person with a wealth
of knowledge who shares her culture. John Dove continued the welcome with a
rich presentation depicting the unique botanical, ecological and geological
features of Texada Island. The next morning we sailed to Texada with a
waterside view of the extensive limestone quarries that have been mined
since shortly after settlers arrived. Our first stop was Marshall Point on
the north end of the Island to view the Juniperus maritima and the flora
that grows along the cliffs. We were delighted to find carpets of Mimulus
guttatus, Plectritis congesta, and Cerastium arvense in full bloom, and
were intrigued with the sculpted dolomite bowls and (basalt) dyke formations
along the shoreline. Vast sweeps of Vaccinium ovatum grow throughout the
Island. We stopped to exam the huckleberry-fir rust Pucciniastrum
goeppertianum infecting the V. ovatum twigs..

Our next stop was to view Jaumea carnosa at Van Anda Lagoon and then to
walk through a carpeted forest rich in Bryophytes and studded with
Fritillaria affinis and Calypso bulbosa. Although we could not gain
entrance to the area richest in Woodwardia fimbriata we were fortunate to
view and photograph a few plants growing near the road.

The next morning our group visited Wildwood Bluffs with Terry Ludwar, and
the second group travelled to view the flora of Deer Lake Bog. The cliffs
provided niches for the Aspidotis densa, Pentagramma triangularis, and
Lomatium nudicaule. A large colony of Zigadenus venenosus was in full
bloom. The excitement was the discovery of the minute least moonwort,
Botrychium simplex by Ksenja Barton. Early signs of Piperia transversa
and Piperia elongate poked through the ground. We were awed by the
stands of mature Arbutus menziesii that dwarfed our humble presence. At
the sphagnum bog, some of the plants identified by the second group included
Myrica gale, Rhododendron groenlandicum, Lonicera involucrata, Kalmia
microphylla, Drosera rotundifolia, Viola palustris, Hypericum anagalloides
and Oxycoccus oxycoccos.

The next Botany BC is planned for 2009, at Muncho Lake on the Alaska
Highway.

ILLUSTRATED KEY TO RACOMITRICEAE OF OREGON ON LINE

From: David Wagner [davidwagner@mac.com]

I have published (posted) an illustrated key to the Racomitrioideae of
Oregon on the web site of the Oregon State University Herbarium:

It covers the four genera of Racomitrium s.l. as treated by Ochyra and
Bednarek-Ochyra in the first part of mosses in the Flora of North America
(vol. 27, part 1, of FNA). The key also covers all species presently known
from California and most of those from Washington state. The key has been
written with vegetative characters as the primary characters in each lead,
with reproductive structures being secondary, so that sterile material can
be identified. I recommend printing out the first part, the Introduction and
Explanation, for detailed instructions on the use of the key and a
discussion of the group.

This is a standard dichotomous key formatted for web browser navigation.
Each page in this key is a couplet with two contrasting leads. The picture
above the lead illustrates the primary character.
The moss green button at the left of the lead links to the next couplet or
to a species page. Each species page gives pertinent synonyms, diagnostic
characters and hints for differentiating look alikes, habitat and
distribution, additional illustrations, and comments.

All pictures on the key pages and the species pages are thumbnails, low
resolution versions of the images for rapid downloading. Click on a
thumbnail to see a larger image. These higher resolution images may be be
larger than your screen depending on your browser settings.
They have been saved at 1000 pixels high to retain reasonably good
resolution. Use your back arrow, "Show the previous page," to return to the
page on which the thumbnail was located. All images used in the key are
repeated on the appropriate species page. Most species pages have many
additional illustrations, over 170 photomicrographs are incorporated into
this document.

At the top of every key page there is a line of breadcrumbs. This is a
series of links to the leads in each couplet taken to arrive at this page.
It is a shorthand record of choices made. You can go back to any step in the
keying process by clicking on the appropriate phrase in the breadcrumb
trail. Clicking on the first breadcrumb will take you back to the start of
the key.

The web key works best with a fast, broadband connection, otherwise the full
resolution photomicrographs will be slow to load. An alternative to using an
internet connection to the web based version is installing the key on your
hard drive from a CD, which I'll provide to anybody in the U.S. for a
donation to cover costs of copying and mailing (say, $5).

I want to give my sincere thanks to Aaron Liston, Director of the O.S.U.
Herbarium, for posting this key. I would appreciate receiving critical
comments on this document.
